To allwkom it may, concern) J H Be 'itknown thatl, PAUL J. DAH'M, a citizen of the United States, residing at Fort Wayne, in the county of Allen andvState of Indiana, have invented new and useful Improvements in Roofs and Methods of Laying the Same, of which the following 1s a specification. v he invention relates to the art of laying'shingles and its object .is to provide a novel method of laying interlockin shingles whereby they are "posltively locke in pos i tion and can neithercurl or be turned up by the wind. v s

.The invention consists in a shingle hava slot in one corner in which slot the next adjacent shingle is engaged so that. the

- adjacent shingle overlas the first shingle "trated in the accompanying drawings in which a a g Figure 1 is a plan view of a shingle con below the slot and un erlaps the portion thereof above the slot. a

Anembodiment of the invention is illusstructedin accordance with the invention,

- and Fig. 2 a plan view of a section of. a roof *ance with 111 having the s inglesthereon laid in accord"- invention. 1 The shing e 1 is formed of. any suitable flexible or pliable material and in any desired size and shape, the rectangular ,form I shown being illustrative only. A slot 2 1s verse course are; substantiallyin alinement,

formed in one corner of the shingle and extends inwardly I from one edge of the shin le preferably at a selected angle to-- war the adjacent edge. Preferably an opening 3 is formed" in the shingle at the inner end of the slot to formfa guide in i applying the next shingle and providing space for horizontal expansion or contraction.

In Fig. 2a.. method of laying he shingles "is illustrated. Each shingle is 7 formed with the slot 2 and the aperture 31 as in Fig. 1. The view illustrates a section of a roof at the lower left corner thereof,

so that along the left edge alternateshingles 4 are substantially half as wide as the remainder thereof. In laying the shingles one of the shingles 1 is fit at the corner ofxthe roof and a nail or other suitable device 5. is driven through the section 6 below the slot 2 and into the supporting material be- '.low. A second shing 'i l..1. nder the rightside of the shingle 1 and edge, of each 1 is then inserted" that overla sit so that water an shingles in each .-i'ow 1 Application filed June 12, 1925.

' in the 510i 2 until die left edge ofthe shingle 1f abuts the end of the slot'or the-wall. of

the aperture 3. A nail or other securing means 7 1s then driven through the overlapping edges of the two shingles above] 1 that is above the-slot. The first shingle at of the secondcourse is laid on the shingle 1 at the selected distance above the lower edge 0t" the shing}: 1 and the section 6 there ofis secured as fore described; .A shingle 1 is then inserted under'the right ed e of the shingle 4 and inthe slot-an anai 7 is driven through the overlapping portions of the two shingles. The roof is entirely covered in this manner and each shingle is v firmly locked to its neighbor so that the lower edge will not turn up or curl up, one

' lower corner of each shingle being securely P TE- /om- E';-

held by its-overlap ing nei hbor and the f other lowerfcorner tening'means. At the same time allnails ing he d by the fasin any shingle are covered updoy the shingle snow'cannot reach t em. However, the shingles may be of such size and so laid to the weather that some of'the nails may be exposed.

The edges 8 of the shingles of each transwith the corresponding edges of the shingles The shingles, as shown 'at 9, in=Fig. 2, Y

may be of such size and arrangement that three of them overlap, thus a ordin .ditional security against leaking andfa to the rigidi on the roof. v

Whatlclaimijsz f 1. A roof including a base-andshingles laid thereon in horizontal rows, each of said shingles being of uniform size'and rectangm.

lar'contour, the vshingles be I laid .wlth' 1 their bottom ed 'es horizon'ta and. their side edges, vertica the bottom edges of-the being horizontally alined, each. shingle havlng a singlediagonal slit extending from a PDlIlt on one side edge adjacent the bottom edge downwardly-and inwardly ofthe shingle, the remaining side shingle continuous and being inserted in the slit of the laterally adjacent shingle with the part below the slit underlying the inserted edge. I

2. A roof including a base and shingles laid thereon in horizontal rows, each of said shingles being of uniform size and rectangular contour, the shingles being laid with their bottom edges horizontal and their side edges vertical, the bottom edges of the shingles in each row being horizontally alined, each shingle having a single diagonal slit extending from a point on one side edge adjacent the bottom edge downwardly and inwardl of the shingle, the remaining side edge 0 each shingle being continuous and being inserted in the slit of the laterally adjacent shingle with the part below the slit underlying the inserted edge, the shingles in one row being arranged in staggered relation to cent row.

In witness whereof I have hereunto set my hand this 8th day of June, 1925.
